Something fishy going on? Recent discovery hints at northward shift in fish distribution

Researchers have discovered an individual Eleotris oxycephala in Akita Prefecture, Japan, which is the northernmost record of this species. The juvenile was discovered in the Yoneshiro River system and likely reached the river from the south via larval dispersal in the Tsushima Current. This possible range expansion of Eleotris oxycephala may be linked to increasing water temperatures.
